Description

[Detailed description of the invention] This invention combines a roll of strip material, such as a continuous plastic bag, in which a break line without a complete cut is formed for each unit of use, and a holder that rotatably stores the roll. The holder has a main body and a lid hinged together at one edge thereof, and has a gap between the edges on the other side with a width that allows the strip material to be pulled out when the lid is closed. The present invention relates to a roll with a holder that allows the strip material pulled out from the material to be cut and used for each use unit, that is, for each break line position.

Conventionally, rolls with holders related to rolls of strip material that have a break line that does not have a complete cut for each unit of use, such as continuous plastic bags and toilet paper, have not been as sharp as expected when used. For example, if the user stops the rotation of the roll with one hand or brakes the rotation of the roll or the running of the strip by mechanical means, the roll breaks easily and is broken by tearing at the corresponding break line. It is used for each usage unit.

Next, the roll with a holder according to Utility Model Application No. 139374 eliminates the disadvantages and inconveniences mentioned above,
In other words, by simply pulling the strip out of the holder in one predetermined direction, the strip can be reliably cut and used in units of use. It has a configuration in which a chevron-shaped protruding cutter is provided in the widthwise center of the gap from which the material is pulled out, and therefore, the cut end of the strip material on the holder side that is broken by the protruding cutter is separated on both sides of the protruding cutter. It will be in a state where it protrudes (exposed) from the gap. Therefore, when cutting out the next unit of strip material, it is normal to pinch the cut end of the strip material away from the protruding cutter. It ends up being pulled out unevenly and twisted, making it difficult to pull out and looking bad, and the breaking action of the breaking line due to the brake action part and protruding cutter is uneven, resulting in inconsistent breaking action, which makes it difficult to use and look good. Less than good.

Therefore, the purpose of this invention is to simply pull out the rolled strip material from the holder in one predetermined direction with a single touch operation, so that the strip material can be reliably cut and used in units of use. At the beginning of pulling out the strip material, it is possible to pull it out by always pinching the center part in the width direction of the cut end of the strip material, and therefore the strip material can be pulled out uniformly over its entire width, making it easy to pull out and without brakes. It is an object of the present invention to provide a roll with a holder which is improved so that the breaking action of the breaking line by the action part and the protruding cutter is always constant and the roll is easily broken.

The ultimate purpose of this invention is to combine a roll of strip material with a break line without a complete cut for each unit of use, and a holder that rotatably stores the roll. In the roll with a holder, the lid and the lid are hinged together at one edge thereof, and a gap is formed between the edges on the other side with a width that allows the strip material to be pulled out when the lid is closed. ) A notch for a drawer knob is provided at the center widthwise of the other side edge forming the above-mentioned gap of the holder, (b) a chevron-shaped protruding cutter is provided at each of the left and right end portions of the above-mentioned notch; ) A brake acting section is provided on each of the left and right sides of the widthwise central part of the gap, which locally applies a braking force to the pull-out of the strip material, (d) A braking force is provided between the left and right chevron-shaped protrusions and the left and right braking force. The object of the present invention is to provide a roll with a holder characterized by the following configuration, in which the relative positions are straight forward and backward in the passing direction of the strip material.

In other words, the roll with holder of this invention has cutouts arranged and sized so that the cut ends of the remaining strip material can be pinched on the holder side, protruding cutters are provided on each of the left and right sides of the cutouts, and the strips are passed through the cutouts. As long as you pinch the cut end of the material, you can pinch the center part in the width direction of the strip material, and in the process of pinching it with one hand and pulling it out, you can pull it out uniformly over the entire width of the strip material and break it with a constant breaking action from the break line. It is characterized by the fact that it is possible to do so.

Next, this invention will be explained with reference to illustrated embodiments.

1 to 4 show a roll with a holder, which is a first embodiment of this invention. In the figure, 1 is a break line 2 that is all perforated for each unit used and does not have a complete cut...
A roll 3 of the strip material 1' formed with the above-mentioned roll 1
It is a holder with a container structure that can be opened and closed to rotatably store.

The band material 1' is a so-called continuous plastic bag, and a heat seam line 4 forming the bottom of the bag is parallel to the break line 2, slightly ahead of the break line 2 that connects the individual bags that are used as units. It is formed.

The holder 3 has a main body 3 whose shape is approximately equal to that of a long and narrow cylindrical container that is large enough to accommodate the roll 1, divided in half.
b and the lid body 3c, one edge thereof is formed by a hinge joint part 3a having a thin wall structure (however, this is not limited to this).
When the lid body 3c is in the closed state (FIG. 4), there is a width (the width of the width) that allows the strip material 1' to be pulled out without any hindrance between the facing surfaces of the other side edges 3b' and 3c'. As shown in Figs. 1 and 2, a gap 5 is formed that spans the entire length of the edges 3b' and 3c' and has a width slightly larger than the width l of the strip 1' (Fig. 3 B and C, Fourth
figure). The holder 3 has a claw 3d protruding from the side of the main body 3b, and a locking piece 3f having a hole 3e that engages with the claw 3d is provided on the side of the lid 3c, and when these are engaged, the lid can be closed. 3c is configured to maintain the lid closed state.

Next, reference numeral 10 in the figure indicates the center portion in the width direction of the gap 5, and the edge 3 of the main body 3b forming the gap 5.
b' is a U-shaped drawer knob with a width and depth that allows for easy insertion of a person's fingertips from the outer edge side of the same edge portion 3b' to pinch and pull out the cut end of the strip material 1'. The notches 6, 6 are provided at the left and right end portions of the notch 10, respectively, and are fixed to the edge 3b' of the main body 3b to apply a braking force to the pulling out of the strip material 1'. Brake protrusions 7, 7 are located on the same edge 3b' as described above, and 2 are located on the left and right ends of the notch 10.
Each of these is a protruding cutter which is provided in the form of a chevron that rises upward at a position directly ahead of the two brake pieces 6, 6 in the passing direction of the band material 1' (to the right in FIG. 4). . In addition, the location where the two protruding cutters 7, 7 are located is as follows:
Extended portion 3 that extends the edge 3b′ horizontally outward
b''. These brake pieces 6, 6 and protruding cutters 7, 7 are separate from the holder 3, and have a notch equivalent portion 10' made of soft rubber with a large coefficient. etc., the member 9 integrally formed as shown in FIG. 9' into the recessed part 8
The structure is such that it is tightly hooked onto the web 8' in the direction of the arrow. Brake protrusion 6,6
protrudes from the upper surface of the member 9, that is, from the upper surface of the edge 3b' which is on the same level as this, by a height equivalent to the gap 5 (approximately 1 mm), and locally abuts against the facing surface of the opposing edge 3c'. The belt material 1' is clamped between the belts 1' and a braking force is applied to the pulling out of the belt material 1'. In addition, the brake protrusions 6, 6
The protruding cutters 7, 7 and the extension portion 3b'' are connected to the main body 3.
The three members 6, 6, 7, 7, and 3b'' may be integrated, separate from b.

In FIG. 2, 3g is a semicircular groove-shaped roll receiving portion formed in the main body 3b, and 3h is a peep hole formed in the lid 3c.

By the way, as an example, the band material 1' is a continuous plastic bag, and the unit bag size is 200 mm in width, 300 mm in length, the diameter of roll 1 when new is about 50 mm, and the width of cutout 10 for the drawer knob is about 15 mm. .

Next, the usage and operation of the roll with holder configured as described above will be explained.

For the first time or when the existing rolls are used up, open the lid 3c as shown in Fig. 2 and insert a separately prepared new roll 1 into the roll receiving part 3 of the main body 3b.
Insert and set the strip material 1' onto the tape g as shown in Fig. 4, unwinding it diagonally upward from the bottom.
The lid body 3c is closed with the tip of the locking piece 3f pulled out outward from the gap 5, and the hole 3e of the locking piece 3f is closed.
is engaged with the screen 3d to close the lid. Holder 3
For example, as shown in FIG. 4, the main body 3b is used by placing the bottom part on the support base 11 and fixing it with screws or the like. When the tip of the strip material 1' is pinched at the notch 10 for the drawer knob and pulled out in the ○A direction (horizontal direction) shown by the two-dot chain line in FIG. The two brake protrusions 6, 6 that clamp the lid apply braking force based on the force that holds the lid closed. The braking force acts intensively on both sides of the band 1' at the point (center) where it is pinched by the fingertips, as an equal tension within the width of the band clamping pressure by the two brake protrusions 6, 6. As a result, the portion of the band material 1' within the range of the clamped pressure width where the tension acts intensively is strongly pressed only against the tips of the two protruding cutters 7, 7 located in front of it (the fourth However, the break line 2 of the strip material 1' is attached to the protruding cutters 7, 7.
When it reaches the weak breaking line 2, the tips of the chevron-shaped protruding cutters 7, 7 will surely and easily pierce the weak breaking line 2. Therefore, as long as the strip material 1' continues to be pulled out, the protruding cutter 7 and the brake protrusion 6, which are stuck at the break line 2 as described above, work together to prevent the strip material 1' from advancing, and the break line The break in No. 2 expands, and finally one bag for use can be cut out. As is clear from the above-mentioned effects, the magnitude of the braking force generated by the brake protrusions 6, 6 is not required to be very large in order to break the break line 2.

The usage of this roll with holder is as follows.
In addition to the usage mode shown in the figure, there is another usage mode in which the holder 3 is fixed to the vertical wall 12 and the strip 1' is pulled out approximately horizontally to the right as shown in Figure 5A, and the holder 3 is placed on the stand 13 as shown in Figure 5B. The holder 3 can be fixed to the ceiling 14 and the strip 1' is pulled out substantially vertically upward, or as shown in FIG. 5C, the holder 3 can be fixed to the ceiling 14 and the strip 1' drawn out substantially vertically downward.

Next, FIG. 6 and subsequent figures show examples of different configurations of the holder as other embodiments of this invention.

First, FIGS. 6A and 6B show that the extended portion 3b'' of the edge 3b' of the main body 3b constituting the holder 3 has a notch equivalent portion 10', and two protruding cutters 7 ₁ on the left and right ends thereof, respectively. 7 ₁ is attached to the member 9 ₁ , and the upper surface of the member 9 ₁ is attached to the edge 3.
The edge 3 of the lid 3c is on the same level as the top surface of b'.
Two brake protrusions 6 ₁ and 6 ₁ are formed as protrusions with a height equivalent to the gap 5 at c', and these brake protrusions 6
₁ and 6 ₁ and the upper surface of member 9 ₁ , a configuration in which a band 1' is clamped is shown.

Next, FIG. 7A shows the main body 3 constituting the holder 3.
A notch 102 for a drawer knob is integrally formed in the extended portion 3b'' of the edge 3b' _of b, and chevron-shaped protruding cutters ₇₂ , ₇₂ are integrally formed on the left and right ends of the notch 102, respectively, and on the other hand,
Two brake protrusions 6 ₂ , 6 ₂ protruding in an arched manner are also integrally formed on the edge 3 c ′ of the lid 3 c, and the brake protrusions 6 2 , 6 _{2 and the main body 3 b facing the brake protrusions 6 2 , 6 2 are} integrally formed on the edge 3 c ′ of the lid body 3 c. A configuration is shown in which the band material 1' is clamped between the edge portion 3b'.

In addition, the one shown in FIGS. 7B and 7C has a notch ₁₀₃ for a drawer knob in the extended portion 3b'' of the edge 3b' of the main body 3b, and chevron-shaped protrusions ₇₃ , ₇₃ on the left and right ends of the notch 103, respectively. Although it is common to the one in FIG. 7A in that it is integrally formed, in the case of FIG. 7B, it is separate from the holder 3 and is a soft Figure 7C shows a structure in which two brake protrusions 6 ₃ , 6 ₃ formed in a semi-cylindrical shape using rubber or the like with a large Masatsu coefficient are attached (glued).
₃ and 6 ₃ are attached to the edge 3c' of the lid 3c.

8A, B, and C show a cutout ₁₀₄ for a drawer knob and protruding cutters ₇₄ , ₇₄ on both left and right ends of the cutout, respectively, which are separate from the holder 3, and which are made of soft material. The main body 3b that constitutes the holder 3 includes a member ₉₄ integrally formed of rubber or the like having a large coefficient.
The member ₉₄ is fitted into a recess 16 provided in the extended portion 3b'' of the edge 3b' and is swingably attached by trunnion shafts 17, 17 on both sides. The height up to the edge 3b' of the main body 3b is installed at the same level as the upper surface of the edge 3b' (Fig. 8C), and there is no brake protrusion. B) and the sharp ends of the protruding cutters ₇₄ , ₇₄ generate a moment about the trunnion shaft 17, causing the member ₉₄ to come into contact with the opposing edge 3c', while the strip material 1 It is characterized by the structure that generates braking force by squeezing .

In each of the above embodiments, the protruding cutter 7 is
A configuration in which the central portion of one of the other side edges forming the gap of the holder is extended outward and protrudes in a direction in which it stands upright with respect to the extended portion 3b'', that is, in the drawings of each embodiment, the strip material 1 ' shows a configuration in which the arrow 1 projects upwardly with respect to the direction of passing through the gap 5.

In this case, the strip material 1' is
If the strip material 1' is pulled out in a direction parallel to the forming surface, the user (operator) can always pull out the strip material 1' in a constant direction because the pulling direction is a direction that can be easily and accurately visually recognized. As a result, if the angle, shape, dimensions, etc. of the protruding direction of the protruding cutter are designed appropriately, it will always be easy to pull out when cutting out each unit of use, and the strip material 1' will be less likely to be scratched by the protruding cutter, and it will be reliably cut. It can be cut under the broken condition and used.

In addition, in each of the above embodiments, the extension portion 3
b'' is ensured, the edges 3b' and 3c' do not necessarily require folded parts that protrude outward (horizontally outward in the figures of each embodiment), but simply form the main body. 3b and the other end of the main body portion of the lid 3c may be used as edges 3b' and 3c'.

On the other hand, in FIGS. 9A and 9B, the protrusion cutter 7
₅ , 7 ₅ protrude only in the direction extending the gap 5 forming surface at the other side edge outward, that is, the structure protrudes in the horizontal direction parallel to the direction in which the strip 1' passes through the gap 5. show something Notch equivalent part 10
₅ and the protruding cutters 7 ₅ on the left and right ends thereof, respectively.
7 ₅ is formed on a member 9 ₅ , and the member 9 ₅ is connected to the main body 3.
In this configuration, the strip 1' is pulled out obliquely downward as shown in FIG. 9B.

In addition, in this embodiment, the edges 3b', 3
c' does not necessarily require the folded portion and the extended portion 3b'' that project outward in the horizontal direction, and simply connects the other side of each edge of the main body portion of the main body 3b and the lid body 3c to an edge. 3b' and 3c' may also be used.

Next, FIGS. 10A and 10B show another embodiment of this invention, which is a slip resistance type in which the brake acting part is configured only as a part that locally contacts the strip 1' and generates slip resistance. show something

That is, in the center of the edge 3c' of the lid 3c that forms the gap 5 of the holder 3, there are two pieces that are separate from the holder 3 and made of soft rubber or the like with a large coefficient of elasticity. The brake protrusion ₆₆ is placed at the rear position of each protrusion cutter ₇₆ , ₇₆ so that it slightly protrudes from the lower surface of the edge 3c' but never comes into contact with the edge 3b' of the facing main body 3b. This is the configuration in which it is fixedly attached as shown in Figure 10B).

Therefore, when the strip material 1' is pulled out in the horizontal direction (as _shown by the two- _dot chain line in FIG. The protruding edges 3b', 3c' strongly contact the brake protrusions ₆₆ , ₆₆ to generate a moderate braking force, and the braking force is localized as tension in the strip 1'. Nana brake protrusion 6 ₆ ,
6 Acts intensively on the range of strip contact width according to ₆ ,
In addition, the portion within the contact width where concentrated tension is acting on the strip material 1' is the protruding cutter 7 ₆ , 7 ₆
(indicated by the dashed-dotted line in FIG. 10A). Therefore, when the weak break line 2 of the strip material 1' reaches the protruding cutters 7 ₆ , 7 ₆ , the break line 2 The tips of the protruding cutters 7 ₆ , 7 ₆ are surely and easily penetrated into the holes, thereby ensuring the breakage. The smaller the distance S from the brake protrusion ₆₆ to the protrusion cutter ₇₆ , the closer the angle α becomes to an acute angle and the greater the slip resistance, which is advantageous in use.

In the roll with holder of this embodiment, compared to the push-type brake acting section shown in each of the above embodiments, even if there is variation in the force for closing the lid 3c, or the force changes depending on the usage state. Even if such a situation occurs, it has the advantage of producing a constant slip resistance (braking force) regardless of the situation.

Next, FIGS. 11A and 11B show that both ends 18a and 18b of the C-ring spring 18 are attached to the side walls of the main body 3b and the lid 3c constituting the holder 3, and the hinge joint between the main body 3b and the lid 3c is shown in FIGS. 3a as the center, and both ends 18a and 18b are fixed at a distance _X0 expanded by an initial deformation amount appropriate for maintaining the lid closed state. In the figure, 19 is a retaining wall for the C-ring spring 18, and 20 is a support rib for the retaining wall 19.

In the case of this holder 3, the distance X ₁ between both ends of the C-ring spring 18 is maximum at the vertical position Y ₁ where the lid 3c is opened approximately 90 degrees, and at the maximum lid opening position Y ₂ where the lid 3c is opened approximately 180 degrees. The distance _X2 between both ends 18a and 18b of the C-ring spring 18 is smaller than _X1 . That is, in the opening/closing operation of the lid body 3c, the _Y1 position becomes a so-called consideration point, and when the lid is in the closed state, the C-ring spring 18 exerts an action to maintain the lid in the closed state (and thus a pressing action on the brake application section). When the lid is in the open state, it conversely functions to maintain the lid in the closed state.

Next, in FIGS. 12A and 12B, an elastic locking piece 21 that is curved in a U shape and protrudes in the opening/closing direction of the lid 3c is integrally formed on the side of the lid 3c constituting the holder 3. On the other hand, the locking piece 21 is provided on the side of the main body 3b.
2 shows a configuration in which a substantially rectangular locking frame 22 that enters as the lid body 3c closes is integrally formed. That is, the locking piece 21 has a locking claw 21a, and when the locking piece 21 enters the locking frame 22 to a predetermined depth, the locking claw 21a engages with the lower edge of the locking frame 22. Keep the lid closed. In the figure, 23 is a dowel protruding from the side of the lid 3c, and 24 is a dowel hole formed in the side of the main body 3b at a position corresponding to the dowel 23. The dowel 23 fits into the dowel hole 24. This restricts the positional relationship between the main body 3b and the lid 3c when the lid 3c is in the closed state.

In each of the above embodiments, the protruding cutter is installed on the main body 3b side, but it is not limited to this, and it may be installed on the lid body 3c side. In the example, the main body 3b and the lid 3c
It may be installed on both sides, both of which are included in this invention.

Next, the effects of this invention will be explained.

This idea consists of (a) providing a notch for the drawer knob in the widthwise center of the other side edge that forms the gap of the holder, and (b) providing a chevron-shaped protruding cutter on each of the left and right ends of the notch. (c) A brake acting section is provided on each of the left and right sides of the widthwise central portion of the gap to locally apply a braking force to the pulling out of the strip, (d) The chevron-shaped protrusion cutter on the left and right sides and the above Since the left and right brake action parts are rolls with holders having the following configuration, the relative positions are straight forward and backward in the passing direction of the strip material, so that the following effects are achieved.

First, the braking force applied to the strip material by the locally configured brake acting section is concentrated as tension in the strip material in the range of the strip material clamping pressure width by the brake acting section as the pulling operation is performed. At the same time, the part of the band material on which the concentrated tension is applied, which is within the range of the clamped pressure width, is pressed only to the tip of the chevron-shaped protrusion cutter located directly ahead of the brake-acting part; When a weak break line reaches the protruding cutter, it becomes certain and easy for the protruding cutter to pierce the break line, and as a result of the protruding cutter being stuck into the break line of the strip material, the breakage of the break line progresses steadily, thus, The strip material can be pulled out from the holder in one predetermined direction with a single touch.
You can reliably cut and use each unit.

Second, when cutting the strip material into units for use as described above, you can insert your fingertips into the cutout for the drawer knob and pinch the cut end of the strip material on the holder side. Therefore, it is possible to always pinch the center part of the strip in the width direction, and therefore the strip can be pulled out uniformly over its entire width, making it easy to pull out and without degrading the appearance during the drawing process. , and the breaking action from the breaking line is always constant, making it easy to break.

Furthermore, after the band is broken, the cut end on the holder side is located in the notch for the pull-out knob and protrudes approximately equally on both sides of the protruding cutter, giving it a good appearance.
